A word of caution
Remember, these are high pressure guns! More on this later, I have to get back to work right now.

Hear hear. An explination.
A Mans ability to step forward and lay claim to this would by far gain respect as opposed to us finding out…. 😀
Mistakes happen, it happens to the best of us 😛
I Agree this is a serious failure and think it best the maker come forward on his own.
open and honest communication is much preferred to us figuring it out and then interpreting the hiding for dishonesty.
kinda of an obamanation as I see it.
Walter…
Lets list all the ones who make these and see if we can get csi wok to figure out who done it.. 😆
I beleive in things being out in the open so think we should know who made it simply because If one can do that then so can other’s and maybe they wont be so kind as to stay in one peice when they do – Then again, I dont see an end cap and I wonder how far the baffles went.
One or two monthes ago on russian site guns.ru was post about airgunner’s death – he tested steel tube with high pressure air – more than 300 bar. Tube blasted and sharp piece of metall injured him to head.
🙁
Yeah I would say that shroud was made from beer can mat’l.
Why, to save weight ?
Piss poor design if you ask me, don’t care if your valve is inconsistent or not it should hold up to at least 3-4 times the pressure capable of the gun at max power shouldn’t it ?
If a ladder for example is rated for 350 lbs., I am sure it could actually handle 1000 lbs.
Thats the way things are supposed to be designed, that shroud however is clearly a attempt by someone who didn’t take that into consideration.
Yeah, first time it has happened, what about the next ?
I personally would do a recall on all those shrouds before someone gets hurt!!!!
Who ever made it really needs to think of using thicker material especially if he is going to flute it. from what I could see in the picture the wall thickness looks like it is around 0.070 or a tad more do you know how thick it is
Has this happened to anyone else?
Shadoh, good job, you are correct on your observations.
Wok, I shot the shroud for 2 weeks before this happened. There were a few times it sounded different.
I do think this may have been caused be defective materials. Not design or craftsmanship. The maker never had this happen before. I believe him. If this were a persistant problem, and not a fluke, you all would know about it.
Look, Im new here, Im not naming names because I was treated right. I understand your safety concerns. That is why I posted this. I did read in an older post someone giving advise to find the thinnest wall ali. tube they could to make a shroud with. Um, mabe not? I will let the maker decide if he wants to discuss this openly.
I hadn’t cleaned the rifle. I was shooting a freshly opened tin of 28gr. eun gin’s that were pretty oily, from the factory. I have never heard of desiling being a problem in PCP guns though.
A slower heavier projectile, a spike in velocity due to an inconsistant (stock) valve, a non vented barrel bushing of frame and a defective tube all came together in my back yard at 10o’clock at night! Bang, Im sure the neighbors loved it.
I’m thinking you have a very good point about the fluting and the thickness of the material used, so once again I ask you shooterjoe was the shroud fluted and is that were and why it failed?
all I know is this scares the hell out of me and if it was one of mine I would be the one posting the failure with the statement that I would either be buying back or replacing every one I have sold.
I wanted the builder to p/m me so I could help figure out a permeant fix (and to reassure myself I was using better goods) so something like this could never happen again and hurt someone, but the more I think about it I believe people are in danger if they have one of these then they should be made aware of this and stop using them before something painful happens to someone.
And the creases are where the other flutes are… Looks like almost coke can thickness material where it started to open up… 😯
Looking at the lead dust pattern I believe we can tell that there was at least one baffle a couple inches behind the end of the muzzle. It probably had the same size center hole as the barrel to make sure the shroud stayed centered and was most likely ported so back pressure could flow backward and into the factory shroud of the gun. In front of the barrel you can see at least two more baffle marks.
My guess is that this shroud had 4 or 5 baffles in front of the barrel with another about two inches behind the muzzle. I dont believe that there was an obstruction that caused this failure I think it was due to the thin shroud being fluted. Look where the tear starts and stops. It is an even distance from either end of the shroud. Thats most likely where the fluting started and stopped on the shroud.
Im wondering if you had just cleaned or oiled the barrel?
I had my original rubber-baffled shroud plug up once, and when I shot it just shot thru the endcap. This looks like a gas buildup of the flammable kind.
Looks like to me some kind of obstruction had to occur.
You can see by the amount of lead dust it had been shot several times.
I’d like to know too, but I figured it was being kept silent for a reason… 😕
